I'm betting that will be unlocked by the upcoming "All Mezzed Up." They'll probably be constructable like balconies only inside your house, and they'll use the same set of railings. Just hope they give us some new railings to work with, maybe new stairs as well.

Thanks Erin and PyroSpazz! I thought it would be like the ski chalet or the stilts on the island house and we would be able to do things to it. Oh well, there’s lots of other nice stuff. I’ll have to clear another lot for exploration if I want to keep this balcony then, dang.

I’ve been gone for ages! I thought I was a goner at one point but here I am! I had to pay real money to finish this quest and I’ve missed so much. I’ve been MiIA fir about 7 months.

Welcome back!!

I think the biggest change to game in the time you've been gone has been the ability to add balconies inside houses, although it's not exactly in the game yet. The house template that was the prize for the Christmas quest had a landing in it that is how balconies are made. Coming up in April will be the All Mezzed Up Discovery quest which will make landings available in the game.

Let's see, for hobby events I think it's:Mean Curls (which was just repeated so it may take awhile before it comes around again)Groovers'n'Movers for activewear in September last year followed by another Groovers'n'Movers event for different activewear in October. But the second Groovers'n'Movers event was for the activewear that is from the Activewear Mega Pack so you may already have it.
For Halloween they had a Chocolatier event for previous Halloween's costumes so if you've finished the Night of the Candy Monsters quest you already have those costumes.Street Smarts for clothes for adult female sims happened in January

I didn't finish this one, I had one batch left to get, unfortunately I do not have enough SP to get it myself and I do not spend real life money on the game so it will have to wait until this repeats, which I am sure it will at some point.
